Dynamic Address Allocation for Rechargeable Energy Accumulator Memory Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rechargeable energy storage devices in motor vehicles face challenges in ensuring that only operable memory cells are assigned addresses, as the current method of inputting addresses before integration does not guarantee functionality during vehicle operation and may result in duplicate addresses, leading to inefficiencies and potential errors.
Innovation Solution
Implementing a process where memory cell functionality is checked in the vehicle, with addresses assigned only to operable cells, and regularly reassigned during operation, ensuring that only functional cells are monitored and duplicate addresses are avoided, using voltage criteria to differentiate and manage memory cell states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If addresses are inputted into memory cells before integration into the vehicle, then the addressing process is completed in advance, but there is no guarantee that the memory cells are still operable during vehicle operation and duplicate addresses may be assigned
Solution Approach 1:
The patent transforms the static addressing process into a dynamic one by implementing periodic functionality checks and address reassignment during vehicle operation. The control unit regularly verifies memory cell operability and updates addresses as needed, ensuring addresses remain valid throughout the vehicle's lifetime rather than being fixed at assembly.
Solution Approach 2:
The system implements feedback mechanisms where sensor devices continuously monitor memory cell status and report to the control unit. Based on this feedback, the control unit determines whether memory cells remain operable and whether address reassignment is necessary, creating a closed-loop system that maintains addressing accuracy.
2Reliability
If functionality checks are performed regularly during vehicle operation, then address accuracy is maintained, but additional time and processing are required
Solution Approach 1:
Instead of continuous monitoring, the system performs functionality checks at periodic intervals during vehicle operation. This periodic approach maintains address accuracy while minimizing the time and processing resources dedicated to checking, finding an optimal balance between reliability and time consumption.
3Ease of manufacture
If addresses are assigned to all memory cells initially, then the addressing process is simple, but duplicate addresses may be assigned to non-operable cells leading to errors
Solution Approach 1:
The system performs preliminary functionality checks before finalizing address assignments. During vehicle operation, the control unit verifies memory cell operability before confirming address allocation, ensuring that only functional cells receive addresses and preventing duplicate assignments to non-operable cells.

AI summary
A method for placing addresses in the memory cells of a rechargeable energy storage device for use in a motor vehicle, each of which memory cells includes at least one sensor device and an individualizing device for storing an address. In order to optimize the placing of addresses in the memory cells of a rechargeable storage device, the functionality of the memory cells is checked using the sensor device in the vehicle, an individual address is assigned to each operable memory cell, and the individual address is used to individualize the sensor values made available from the sensor device.
